WOBURN, Mass.--(BUSINESS WIRE)--Frequency
Therapeutics, a clinical stage biotechnology company, today
announced the completion of enrollment in the single dose safety trial
to evaluate FX-322, a first-in-class drug candidate for hearing
restoration from the company’s Progenitor Cell Activation (PCA)
Regeneration platform. The randomized, double-blind, placebo-controlled
trial is assessing the safety of a single dose of FX-322 given by
intratympanic administration in adult patients with stable sensorineural
hearing loss (SSHL) who have a medical history consistent with either
noise exposure or sudden hearing loss.

“We are pleased with how rapidly we were able to recruit patients with
stable sensorineural hearing loss, which is a testament to the support
from our Clinical Advisory Board, as well as the enthusiasm of our
investigators and the participating patient volunteers,” said David
Lucchino, President, Co-founder and CEO of Frequency.

The safety trial is a randomized, double-blind, placebo-controlled,
single-dose, multi-center study of FX-322, which was administered in
patients with stable sensorineural hearing loss and is being conducted
at several leading otolaryngology clinics in the United States. Patients
received either an injection of FX-322 or a placebo in one ear with an
initial follow up visit after two weeks and will continue to be
monitored for the following three months.

“The advancement of FX-322 from our first study in cochlear implant
patients into patient volunteers with stable sensorineural hearing loss
should enable us to open our future studies in the office-based
setting,” said Carl LeBel, Ph.D., Chief Development Officer of
Frequency. “If successful, the current study will position us to advance
to our Phase 2a program where we’ll be looking to identify and
characterize a hearing restoration signal and proof of biological
concept in sensorineural hearing loss.”

clinicaltrials.gov with the identification number: NCT03616223.

ABOUT CHRONIC NOISE-INDUCED HEARING LOSSVirtually all
hearing deficits in humans arise from damage and/or loss of key cells in
the inner ear called sensory hair cells. These inner ear hair cells
convert sound waves into nerve impulses. In adult mammals, unlike birds
or reptiles, inner ear hair cells do not spontaneously regenerate
following injury, although progenitor cells capable of regenerating hair
cells remain present in the ear. There is no approved therapeutic option
for chronic noise-induced hearing loss. Around 48 million people are
affected in the U.S. alone, and the World Health Organization (WHO)
estimates that 1.1 billion children and adults ages 12-35 years old are
at risk for hearing loss from recreational noise. Hearing loss caused by
prolonged exposure to excessive noise is observed in many professional
environments, such as heavy construction sites or military training.
However, repetitive exposure to everyday loud sounds associated with a
busy subway or rail system, emergency vehicle sirens, musical concerts
and the excessive use of headphones at high volumes can have a negative
impact on hearing. Frequency’s therapeutic candidate for noise-induced
hearing loss, FX-322, is a proprietary combination of small-molecules
drugs designed to transiently activate inner ear progenitor cells,
create new hair cells and improve hearing.

ABOUT PCA REGENERATIONTissue regeneration with Progenitor
Cell Activation, or PCA
Regeneration, is a new therapeutic approach to repairing damaged
tissue and restoring health function in a less complex and potentially
safer manner than traditional cell and gene therapy. The approach, based
on discoveries in progenitor cell biology from the labs of Bob Langer,
Sc.D., at MIT and Jeff Karp, Ph.D., at Harvard Medical School and
Brigham and Women’s Hospital, utilizes small molecules to awaken dormant
progenitor cells already in the body and has the opportunity to address
numerous degenerative diseases such as hearing loss, demyelinating
diseases, skin disorders and gastrointestinal conditions.

ABOUT FREQUENCY THERAPEUTICSFrequency Therapeutics develops
small molecule drugs to stimulate cells in the body to reverse
biological deficits and restore healthy tissue. Through the transitory
activation of these cells, Frequency enables disease modification
without the complexity of genetic engineering. Our ground-breaking
therapy uses a proprietary combination of small-molecule drugs that
induce progenitor cells to multiply and create new cells. While
Frequency’s lead program targets hearing restoration, our PCA
Regeneration platform has the potential to touch upon a wide breadth of
disease indications. www.frequencytx.com.
